Hi everybody, I'm trying to get some microarray data for GEO db. In this example , you can see that the ID reference is a number:

ID_REF  VALUE
1   2.335811886e-001
2   0.000000000e+000
3   0.000000000e+000
4   0.000000000e+000
5   0.000000000e+000

Do you know how can I get the gene id for these? Thank you very much in advance
